Used CHEMALUX 300 #9231352 for sale

CHEMALUX 300 is a negative photoresist equipment used in the production of printed circuit boards (PCBs). The system consists of a prepolymer solution and a liquid developer which are selectively exposed to light. When the prepolymer solution is exposed to ultraviolet light, a photochemical reaction takes place which causes precise physical and chemical transformations. The net result is the formation of a highly insoluble, robust polymer film which is resistant to chemical solvent etching. The prepolymer of 300 resist unit is composed of polymethyl methacrylate terpolymer, additives, sensitizers, stabilizers and monobasic or dibasic organic acid salts. The liquid developer is an aqueous solution of an alkaline agent (e.g., sodium hydroxide or potassium hydroxide) combined with surfactants, salts and organic solvents. CHEMALUX 300 resist machine was developed to create high-resolution patterns during the imaging process for use in mass production of PCBs. This resist tool exhibits superior photosensitivity, resolution, and film forming properties. It produces clear images with superior edge definition and achieves high adhesion on a variety of printed circuit board substrate materials such as copper, aluminum, stainless steel, and glass-reinforced polyester. It is most suitable for the production of multi-layer PCBs as it exhibits good through-hole penetration with minimal voiding. This resist asset also features high chemical resistance, providing superior resistivity to a variety of common chemical solvents used to etch features onto the boards. This results in superior etch resolution and increased yield. 300 resist model can be used in both contact and projection printing systems and is compatible with all conventional PCB production processes. The equipment is stable in ambient light and can be stored at room temperature for extended periods of time. Given its many advantages and features, CHEMALUX 300 resist system is widely used in the PCB industry as it provides efficient and economical production of high-resolution patterns with accuracy and repeatability. It is also suitable for the production of rapidly evolving and complex PCB designs. Overall, 300 resist unit is an ideal tool in the development of modern high-precision printed circuit boards.
